Germany – Construction work – Sanierung Von Bahnsteigdächer und Errichtung von Befahranlagen am Bf. Regensburg

The works at the Hbf Regensburg comprise, in LOS1, the renovation of two central platform roofs and, in LOS2, the construction of access systems on the transverse buildings (QH) and the pedestrian overpass (PÜ). The scope of the roof renovation consists of the renewal of the roof waterproofing, corrosion protection, roof lighting, ceilings, and the repair of roof support bases.
